On 1 January 1905, the IRN created the world's first operational submarine fleet around these seven submarines. The first combat patrol sent out by the newly created IRN submarine fleet occurred on 14 February 1905 and was carried out by Delfin and Som, with each patrol normally lasting about 24 hours.
Although experimental submarines had been built before, submarine design took off during the 19th century, and they were adopted by several navies. Submarines were first widely used during World War I (1914â1918), and now figure in many navies large and small.he noun submarine evolved as a shortened form of submarine boat (and is often further shortened to sub). For reasons of naval tradition, submarines are usually referred to as  boats  rather than as  ships , regardless of their size.
